<p>Sets the "safety flag" on if <em class="parameter"><code>is_trusted</code></em>
.</p>
<p>Safety flag is a new concept introduced in
XFCE 4.17. It is basically an additional
execution flag stored in GVFS-metadata.
Unlike the execution flag (+x), it is safe
to assume that this flag did not come from
foreign location (for example, by downloading
an tar archive) and is set by user.</p>
<p>The checksum of the file is stored, and
would be considered "on" only if checksum
matches with the file on execution.</p>
